4 Claims. .(Cl. 101-226) The present invention relates to devices for printing sheet material and for slitting the sheets as printed. lvlore specifically, it relates to devices for imprintingthe surface of the sheet in duplicate and interfitting patterns, and simultaneously, or thereafter, dividing the sheet along the interfitting margin of the two patterns. In one-form of the invention, either the printing operation or the slitting operation may be omitted as desired. j

Further and other objects and advantages will become apparent as the disclosure proceeds and the description is read in conjunction with the accoinpanying'drawings, in which Fig. 1 is a side, elevational View of a preferred 'form of the invention;

Figs; 2 and 3 are, respectively, sectional views on the line 2-2 and33 of Fig. 1;

Fig. 4 is a detail end elevation, partly in section, showing-a further modification;

Fig. 5 is a detail, transverse, vertical section the form of construction shown in Fig. 4;

Fig. 6 is a-detail section on the line 6-6 of Fig.

1; and

Fig. 7 is a detail plan of the printed and slitted sheet as it leaves the machine.

Referring to Figs. 1-3, inclusive, the printing and slitting elements are mountedupon the pe- O ripheries of rollers 10 and 11, respectively. The

printing forms are of like pattern or configuration, each occupying approximately one half of the surface of the roller. The printing roller 10 comprises a pair of disks or annuli 23, 24, which 5 form the ends of the roller and imprint the outer margins of the dual pattern; a central annulus 27 for imprinting the inner margins of the patterns; and connecting bars 25, 26 extending between the for imprinting the intermediate portions of the patterns.

As shown, these elements are configured to print one half of the pattern illustrated in Fig. 7. The printing elements may, of course, be

. changed in form to produce any desired pattern.

In the disclosed embodiment of the invention, the elements 23, 24 are simple disks suitably fixed to the shaft 41a; the element 27 is annular in form and is mounted upon a drum 31 secured to the shaft; and the elements 25, 26 are straight bars shown as formed integral with the element 2'7, and as being attached to the disks 23, .24 through the medium of brackets thereon as 29, 30. For producing the pattern shown in Fig. '7, the element 27 is, of course, of zigzag contour elements 23 and 24, and the annulus 27 and the cutting blade 33 on the roller 11 is of like form.

The drum 31 is annularly channeled as indicated in Fig. 6, the walls of the channel constituting radial flanges and at least one of them, as 36, being beveled to form a wedging surface. The printing element 27"is seated within this channel as are also binding blocks 34, 35 which interfit between the element 27 and the side walls of the channel and are secured to the drum, or

other integral appurtenance of the channel walls, by'any suitable means, such as screws 37. The blocks 34 having outer edges of complementary contour to the wall 36, which is beveled, when drawn down into the drum channel by the attaching screws securely bind the printing form to the drum. The securing blocks 34, 35 will be varied in form to correspond with the inner marginal portion of the printing forms. While the central support for the printing form and binding blocks is shown as an integralchanneled drum, it is obvious that the side walls of the channel are. the immediate supporting means and I may be secured to the shaft in spaced relation by any suitable means.

The shaft 41a carrying the printing roller is mounted in suitable journal boxes 45 and 4511, these boxes being shown as carried by a tank for containing the printing material.

A cutting roller 11 is journaled above the printing roller and cooperates to simultaneously print and slit the'sheet being worked upon. Preferably these two rollers are geared together as indicated at 44, 44a, and power may be applied to them in any suitable manner, as by means of a sprocket chain 22.

One advantage in having the cutting knife on one cylinder and the printing forms on the other is that the slitting is done on the uncoated side of the sheet, and, consequently, the blade isnot 9 dulled by the granular material on the opposite side of the sheet.

There is shown in Figs. 1 and 3 means for regulating the pressure between the two rollers. To this end the shaft 41a of the roller 10 is journaled in the boxesv .45, 45a, which are vertically slidable in crossheads 46, 4'7, forming parts of the frame of the machine, each of the boxes resting upon a screw rod 48, upon which is mounted a nut 49 having the form of a worm gear and resting upon a bracket 50 attached to the side wall of the tank 40. A worm shaft 51, suitably journaled in the frame of the machine, cooperates with the gear 49 and carries a hand crank 52.

This adjusting mechanism is duplicated in order to control both ends of the roller, and each of the shafts 51 is provided with a sprocket wheel same construction as the rollers 10 and 11, but

are spaced apart to receive between them an idler roller 56, about which the sheet X of material operated upon turns. The printing roller 54 is urged upwardly, and the slitting roller 55 is urged downwardly into cooperation with the roller 56 by adjusting mechanism as shown and described in connection with Figs. 1 and 3. In the construction shown in Figs. 4 and 5, the printing and slitting rollers are, of course, assembled in peripheral relation, and the idler 56 is of such size that the printed pattern imprinted by the roller 54 is brought exactly into proper relation with the slitting blade 33 carried by the roller 55.

This embodiment of the invention has the added advantage that either the printing or slitting roller may be used independently of the other.

I claim as my invention:

1. For use in a machine adapted to apply a pattern to a strip of roofing material, coated on one side witha weatherproof protective surface, and simultaneously with the application of the pattern to cut the strip longitudinally into roofing elements, the combination of a pair of rollers between which the strip is passed, the roller contacting with the coated side of the strip being provided with raised printing bars on its periphery corresponding to the pattern to be applied, and the roller contacting with the uncoated side of the strip being provided with an annular cutting knife for cutting the strip longitudinally into a plurality of roofing elements.

2. A machine for applying a pattern to a strip of roofing material coated on one side with a weatherproof protective surface, and simultaneously with the application of the pattern cutting the strip longitudinally into roofing elements, said machine comprising a pair of rollers between which the strip is passed, the roller contacting with the coated side of the strip being provided with raised printed bars on its periphery corresponding 'to the pattern to be applied, and the roller contacting with the uncoated side of the strip being provided with an annular cutting knife for cutting the strip longitudinally into a plurality of roofing elements, means for driving the rollers in opposite directions at the same peripheral speed, and means for supplying printing material to the printing roll. 7

3. .A machine for applyinga pattern to a strip 9 of roofing material coated on one side with a weatherproof protective surface, and simultaneously with the application of the pattern cutting the strip longitudinally into roofing elements, said machine comprising a pair of rollers 9 between which the strip is passed, the roller contacting with the coated side of the strip being provided with raised printed bars on'its periphery corresponding to the pattern to be applied, and the roller contacting with the uncoated side 1( of the strip being provided with an annular cutting knife for cutting the strip longitudinally into a plurality of roofing elements, means for driving the rollers in opposite directions at the same peripheral speed, and means for adjusting the '1! rollers relative to each other.

4. The method of applying apattern to a strip of roofing material coated on one side with a weatherproof protective surface and simultaneously with the application of the pattern cut- 1 ting the strip longitudinally into roofing, elements, said method including passing the strip between cooperating printing and cutting rollers whereby the pattern is printed on the coated side of the strip and a longitudinal cut is simultanel ously made on the opposite side ofrthe sheet, dividing the sheet into a plurality of roofing elements.
